SPRINKLING- SYSTEM AND SPRINKLER.

Application filed June 28,

T 0 all whom it may concern:

Be it known that I, FRANK B. ALLEN, a citizen of the United States, residing --at' Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented cer-- tain new and useful Improvements in Sprinkling Systems and Sprinklers, of which the following is a full, clear, concise, and exact description, such aswill enable others skilled. in the art to which my invention appertains to make and use the same. Y

My invention relates tosprinkling systems in general and to sprinklers in general, but my invention is especially adapted for use in connection with ash hoppers associated with large furnaces.

Heretofore sprinkling systems and sprinklers have been used for wetting ashes and ash flues which are subject to a number of objections. For example, the water supplied from sprinklers has been delivered in such form as to form puddles in one place and leave dry areas at diflerent points; also in the-sprinkling systems used heretofore, the supply mains appear in the ash flues themselves.

Heretofore when the sprinkling orifices have become clogged, no. provision has been made for remedying the defect, except by. awkward and impractical methods, or by removing the sprinkler element; the orifices through which the water passes are not readily accessible for cleaning purposes and are not so constructed as to be adjustable.

Among the objects of my invention are.

To provide a sprinkling system in which the water pipes are not exposed to the heat of the ash hoppers or to the ashes.

To provide in a sprinkling system a sprinkler in which the interior thereof and the removable parts are accessible from the outside of the hopper wall regardless of the amount of ash in the hopper.

To provide in a sprinkling system of the above character an arrangement whereby each sprinkler may be disassociated from the sprinklers of the rest of the system.

To provide a sprinkler which may I be opened from the rear for the purpose of removing clogging material, and for ad. justing or replacing the removable nozzle.

To provide a sprinkler of the above char- A acter, the construction of which is such that the water is scattered in a manner to avoid puddling. 4

To provide other details of improvement 1922. Serial to. 571,405.

tending to increase the efliciency and serviceability of a sprinkling system, and of sprinklers of the above character.

To accomplish the foregoing and other useful ends, my invention makes use of means hereinafter more fully set forth and claimed.

Referring to the accompanying draw- 1ngs- Fig. 1 shows the layout of a sprinkling system embodying my invention, and its relation to the boilers and ash hoppers, and the relation of the sprinklers to each other.

Fig. 2 is an end view of one of the sprinklers shown projecting into one of the ash hoppers, and showing the connection to the water main.

Fig. 3 is a bottom plan view of one form of the sprinklers, and

Fig. 4 is a section on line 4-4, Fig. 3.

Referring more in detail to the accompanying drawings, the water pipe 2 is shown in the room adjacent to the ash hoppers, which room is above the floor et below which the ash hoppers are located. From the water main 2 Ishow a series of taps or branches 3 extending from the water main to the individual sprinklers. In each of these, branches are provided a shut-off 5 and a union 6. The,frame 7 of the sprinkler is secured by bolts 8 to the under side of floor 4.

In the floor there'is an opening 9 which registers with'the open rear end of the frame 7 which communicates with the chamber 10 within the frame. This: chamber 10, as will be seen, slants at anangle of approximately 45-degrees with the floor. The object of this construction is to dispose the sprinkler at this'angle in order to facilitate the scattering of the water spray. This frame 7 is of reduced size at its lower end and is hollowed out to form a second chamber 12. Between this chamber and the chamber 10 there is a' neck which is provided with threads 11. which threads are adapted to receive the plug 13 for shutting off the chamber 12 from the chamber 10. This plug may be either removed or screwed in position by inserting a suitable Wrench or other device through the hole'.

9 in the floor.

It will be understood, of course, that a i cover of any suitable charactermay be placed over the hole 9. Open-in into the chamber 12 is a duct 14: whic extends 'llO through a spur 15 in the frame 7 and terminates in a threaded orifice 16. This orifice is located in juxta-position with an opening in the floor through which the branch pipe 3 leading to the water main extends, said branch pipe 3 being screwed to the sprinkler at the orifice 16.

In the forward or head end of the frame 7, I provide an orifice 17 in which is fitted .tion it will be seen that the water flows from the branch pipe 3 into the chamber 12. 'By disposing the duct 14 at an angle to chamber'12, a rotary motion is imparted to the water as it enters the chamber.-

This rotary motion enables water to scatter as it leaves'the orifice 20 much more efi'ectively than would be otherwise the case.-

It will be observed that the nozzle 18 3 is placed in position without any locking mechanism the piece being held in place by reasonably close fitting and by pressure of the water from the rear. However, I contemplate the use of any suitable holding arrangement such as screw threads or the like wherever necessary. The object in leaving the nozzle without any locking mechanism is to facilitate the ready removal thereof. I also contemplate the substitution of one nozzle for another whenever a change in the size of the orifice 20 is deemed necessary due to variations in pressure of the water, or due to the necessary increase in the normal discharge of the sprinkler.

It will be seen that with the construction and arran ment shown and described, I provide a ighly eflicient sprinkling system and sprinkler. The arrangement provides means whereby the water may be cut off from any individual sprinkler whenever necessary, as for example, for the purpose of adjustment or for the purpose of cleanin any obstruction that may have crept into the chamber 12 or into any part of the sprinkler, or for changing the nozzle. This can all readily be done by shutting off the water at the shut-ofl 5, and by removing the plug 13 by way of the hole 9 in the floor.

After the necessary cleaning, adjusting or substituting operation has taken place,

the plug 13 is restored to close up the chamber 12.

What I claim as myiinvention is- 1. In a sprinkler system for ash hoppers,

in combination, an ash hopper, a wall covering a portion thereof, a sprinkler in the hopper secured to the said wall and a source of sprinkling fluid outside the said hopper and connected to the said sprinkler, the interior of the said sprinkler being accessible thru the said wall from outside the hopper.

2.
